QUANTUM TRANSPORT IN THE MARKOVIAN AND NON-MARKOVIAN ENVIRONMENT.

In this paper, we report on a detailed study of how decoherence assists quantum trans-port in a dimer system. By carrying out analytical and numerical computations, we find that the decoherence induced by a Markovian (memoryless) environment only assists the maximum probability of quantum transport in the dimer system to 50% not close to the unity, and the decoherence induced by a non-Markovian environment with perfect mem-ory (infinite memory time) can improve the maximum probability of quantum transport to unity. The combination of non-Markovian decoherence and Markovian decoherence assist the quantum transport more effectively. Comparing the classical environment with the quantum environment, we obtain that the classical non-Markovian environment can-not assist the maximum probability of quantum transport close to unity. In addition, enlarging the quantum environment can improve the maximum probability of quantum transport. [ABSTRACT FROM AUTHOR]
